IBAG-TYING DEVICE.

Specification of Letters Patent.

Patented Mar. *7, 1911.

Application led .Tune 1, 1910. Serial No. 564,408.

To all whom it may concern:

Be it known that I, FERDINAND MUcnnuY, a citizen of the United States, residing at Easton, in the county of Northampton and State of Pennsylvania, have invented certain new and useful Improvements in Bag- Tying Devices, o-f which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to certain new and useful improvements in bag tying devices and it has for its objects among others to provide a simple and efficient device easily operated and by which the bags may be quickly and expeditiously tied.

I provide a device embodying a movably mounted member in which is reciprocatingly mounted the means which serve to cause the tie to embrace the mouth of the bag and to fasten such tie thereabout by one manipulation. The construction is such that after the mouth of the bag has been fastened, the downward movement of the bag caused by the weight thereof serves to cause the said movable member to drop, after which the tying devices are returned to their normal position, another tie placed in position and the operation repeated.

Other objects and advantages 0f the invention will hereinafter appear and the novel features thereof will be particularly pointed out in the appended claims.

The invention is clearly illustrated in the accompanying drawings, which, with the numerals of reference marked thereon, form a part of this specification, and in which-- Figure 1 is a perspective View showing the application of the invention. Fig. 2 is a view showin@r the position of the parts after the tie has tbeen secured about the mouth of the bag. Fig. 3 is a perspective view of the articulated tie-holding member. Fig. 4 isa vertical cross section on the line 4 4: of Fig. 3. Fig. 5 is a perspective view of the tie before it is applied to the tie-holding member. Fig. 6 is a top plan of the bag with the tie fastened about the mouth thereof. Fig. 7 is a top plan showing a slightly modified form of construction of the articu lated member and the means for bending and clenchingthe tie. Fig. 8 is a side 'view of the modiiied form of Fig. 7. j

Like 'numerals of reference indicate like parts throughout the several views.

Referring to the drawings, 1 designates a suitable support which may be a standard rising from the floor or other base, or otherwise aflixed in the desired position.

2 is a block or member hinged to the upper end of the support 1 by suitable means, as a hinge 8, the adjacent faces of the block and support upon one sigle of the hinge being square faced or parallel, as seen at 1, while upon the opposite side they are beveled, one or both, as seen at 5.

6 is a bar mounted fo-r reciprocation through a suitable horizontal aperture in the block 2 and having one end turned at an angle, as seen at 7. The other end of this arm or member 6 is surrounded by a spring 8 engaging at one end against a suitable collar or sto-p 9 on the member 6 and at the other end against the adjacent face of the block 2. The upturned end 7 of the bar 6 is secured by bolts or suitable means 10 to one member, and that preferably the center one, of the articulated device which is adapted to hold the tie. This device comprises members 11 hinged together, as at l2, with a vertical joint leaving the acting face of the articulatedmember practically smooth. In a suitable recess or channel in the rear face of this articulated member is a spring 13 retained at it-s ends in any suitable manner, as by suitable bails or clips 111, as seen in Fig. 3. The opposite face of this articulated member is also provided with a recess or channel in which is placed the tie member 15 which is preferably of substantially the form seen in Fig. 5, having one end bent at substantially a right angle to the main or body portion of the tie, as seen at 16, and this angular portion provided with a slot 17 extending in this instance vertically. The body of the tie member is preferably tapered, as seen in Fig. 5. It is inserted endwise into the channel with both ends projecting, as seen in Figs. 1 and 3. It may be retained against accidental displacement during bend ing by any suitable means, as by the clips or the like 18, whichare of sufficient height to hold the tie against displacement during bending but allowing of automatic withdrawal of the same when the actuating member is caused to return to its normal position after the tie has been clasped about the mouth of the bag.

19 is a bar mounted for reciprocation through a suitable opening in the block 2. At one end it is provided with a rack or toothed portion 2() with which is adapted to engage a toothed wheel 21 carried by a shaft 22 mounted ina Isuitable bearing 25:5 and provided. with a crank shaft. 24, whereby it may be revolved. The bearing 23 may be affixed to any suitable support. 'l`he bar 1S) has pivotally coni'iecled therewith near its end by a suitable pivot 25, the crossed curved arms or levers 2G which, at their outer ends, carry the vertical rollers 27, as seen best in Fig. l. These rollers bear against. the rear face of the articulated member, as shown. rlhe other arms of the crossed levers which are shorter are arranged upon opposite sides of the har 19 and between said ends and the adjacent edges of the bar are 'lisposed springs :28, preferably coiled springs, as shown.

The operation as follows: 2.() designates a discharge spout through which the material to be fed to the bag is discharged, 3() being the terminal or funnel portion thereof.

31 the bag, the mouth 32 of which is placed over the funnel 30, as seen in Fig. 1.

The material is fed into the bag in' any of the well-known ways and when the same is full, the shaft 22 is turned by its crank 24, so as to move the arm 19 in the direction indi cated bythe arrow in Fig. 1. As this arm is thus moved, the rollers 27, pressing against the spring 13, move the articulated member bodily in the direction of the said arrow, and as the arm G is connected with said articulated member, this movement tends to first force the arm G in the direction of the arrow in said Fig. 1 and press the center portion of the articulated member l1 against the adjacent face of the bag, the said arm 6 moving up against the tension of its spring 8. Further revolution of the shaft 22 moves the arm 19 in the direction of the arrow, the rollers following the articulated member which is curved thereby around the mouth of the bag and after the said rollers pass the diametric center' of the mouth of the bag, the springs 28 tend to force the arms toward each other, the rollers following such movement and the articulated member is caused to embrace the mouth of the bag and by continued move-Y ment, the smaller end of the tie member 15 (it being understood that said tie member is, of course, made to encircle the mouth of the bag with the articulated member) is first forced through the slot 17 of the angular portion 16 at the other end of the tie and further continued movement of the bar 19 serves to force the said end around said member, as seen in Fig. 6, so as to clench the same. During such movements, the block 2 has been retained in its elevated position, that seen in Fig. 1, but when the mouth of the bag has been tied and the parts moved into the position necessary to accom- .plish such a result, the preponderance of weight causes the block 2 to move downward into the position seen in Fig. 2, the

bag heilig moved do\\'n\\"ard from its en gagemei'it with the funnel member 30 of the discharge spout.. The shaft 22 is then revolved in the opposite direction, which causes the articulated member to be witl'idrawn from its engagen'ient with the tie, the spring 13, aided by the spring 8, serving to restore the parts to their normal position, that seen in Fig. 1, when they are ready to receive another tie and the operation is repeated.

lVhile, when. en'iploying lightand thin ties. the rollers and the actuating means therefor hereinbefore described will be found suliicient for bending and clenching the tie about the mouth of the' bag, for heavier and less resilient ties, it is desirable to employ additional means for insuring the clenching of the ends of the tie about the mouth of the bag. The articulated member, its spring and the other parts are substantially the same, but upon one of the rollers I affix a jaw or curved plate 33 following substantially the contour of the curved lever carrying the roller, as seen in Fig. 7, so that the end or point of this jaw moving in advance of the roller engages t-he end of the tie after it has passed through the slot 17 of the angular portion of the tie and forces the same down and against the adjacent portion of the tie, so that the ends thereof are firmly clenched, as shown in Fig. 6.
